Step by Step Implementation

Step 1: Create a New Project

To create a new project in the Android Studio Canary Version please refer to How to Create a new Project in Android Studio Canary Version with Jetpack Compose.

Step 2: Adding TextView in MainActivity.kt file

Navigate to the app > java > your app’s package name and open the MainActivity.kt file. Inside that file add the below code to it. Comments are added inside the code to understand the code in more detail.
